Abstract

PURPOSE: To attenuate pulsation and reduce noise by closing the fluid inlet extreme end of a combined main pipe and connecting control pipes from this close end at specific intervals.
CONSTITUTION: One end 3a (inlet end of transport fluid) of a combined main pipe 3 is closed with a lid body 12 and an exhaust bath is connected to the other end 3b. Assuming that the pulsating wavelength is the respective control pipes 8W11 with pumps 4W7 are connected at the position of [2(n-1)+1]λ/4(n: 1, 2, 3,...) from the close end of the main pipe 3. Since the progressive wave which is discharged from each of the control pipes 8W11 is interfered and attenuated by the reflecting wave from the close end, the pulsation from each control pipe is not transmitted to the other end 3b of the main pipe. As a result, noise and vibration can be reduced.
